We get a lot of questions about service scope, routine tasks, filter care, cleaning steps, and gentler sanitation options.
Here’s what we see most often at Dolphin Pool Services.
Weekly service usually covers skimming leaves, vacuuming visible debris, and brushing pool walls and tiles.
We test and adjust chemicals, check water level, and inspect pumps, filters, heaters, and lights.
Our technicians empty skimmer and pump baskets, backwash or clean filters when needed, and report any repair needs.
We log our work and communicate recommended fixes or upgrades.
Monthly costs depend on pool size, frequency, and services.
We provide written quotes tailored to each pool and property.
Test water at least twice a week for chlorine/bromine, pH, alkalinity, and calcium hardness.
Adjust chemicals to keep pH near 7.4 and free chlorine in the right range for your sanitizer.
Run filtration daily—usually 8–12 hours—check circulation, and remove organic debris quickly.
We recommend scheduled professional visits to prevent scale, algae, and equipment strain.
Clean cartridge filters every 1–3 months depending on debris and usage.
Sand filters need backwashing every few weeks; DE filters require backwashing and DE recharge as pressure rises.
Replace filter media or cartridges when they show wear or lose efficiency—often every 1–5 years depending on type and care.
We check filter condition on each visit and let you know when it’s time for replacement.
Start by skimming and brushing surfaces, then vacuum to remove settled debris.
Clean skimmer and pump baskets and check filter pressure before adjusting run times.
Test water and add chemicals in this order: alkalinity, pH, sanitizer, then shock if required.
Follow product labels and allow circulation time between additions.
We follow strict safety and dosing practices and document each step.
Salt chlorine generators usually create a softer feel in the water when we manage them correctly. You won’t notice those harsh chlorine spikes that sometimes bother sensitive skin.
We also use mineral systems, ozone, and UV options to help lower chlorine needs. These additions can really take the edge off skin and eye irritation.
If you have sensitive skin or eczema, we’ll check your pool’s pH and sanitizer levels to keep everything balanced. Our team at Dolphin Pool Services always looks for the best way to make your pool gentle and safe for everyone.
